WHAT=92S NEW Robert L. Park Thursday, 9 Aug 2012 Washington, DC 1. THE LONG, HOT SUMMER: WHERE HAS WHAT=92S NEW BEEN? You don=92t really want to know. Nevertheless, What=92s New lives and th= ere=92s=20 a lot we need to catch up on, so let=92s get started.=20=20 2. CURIOSITY: THE ADVENTURES OF A VIRTUAL ASTRONAUT. Launching the Mars Science Laboratory Rover on a 150,000,000 mile journey= =20 to Gale Crater on Mars was a lot easier than landing it safely once it go= t=20 there, but NASA pulled the incredible landing maneuver off perfectly.=20=20= After all, this was science-NASA, the part of NASA that explores the moon= s=20 of Saturn with unmanned spacecraft, and uses space telescopes to discover= =20 exoplanets orbiting distant stars. The new Rover, which also answers to t= he=20 whimsical name =93Curiosity,=94 will explore Gale Crater for one Martian = year=20 (687 Earth days) looking for evidence of extraterrestrial life. This may= =20 call for a sample return mission, but it=92s still the greatest quest in=20= science. There are, however, two NASAs. Curiosity is also called on to=20= evaluate the =93habitability=94 of Mars. That=92s a concession to astron= aut- NASA, the larger =93half=94 of NASA=92s budget. Astronaut-NASA dominated= the=20 space program from Apollo to the Space Shuttle and the International Spac= e=20 Station, which trapped astronaut-NASA in low-Earth orbit. But as I pointe= d=20 out in my article in Slate Magazine on Monday, the astronaut program simp= ly=20 must not be allowed to control NASA as long as there is a search for=20 extraterrestrial life.=20=20=20 3. CELL PHONES: PROTECTING AMERICA FROM MICROWAVE PHOTONS?=20 Congressman Dennis Kucinich (D-OH) has introduced the Cell Phone Right to= =20 Know Act (H.R. 6358) requiring radiation warning labels on mobile=20 communication devices. If passed, the warning labels will inform consume= rs=20 of the SAR (specific absorption rate) of their device. But knowing the S= AR=20 of their cell phones will be no help to consumers anyway, since numerous=20= studies find no evidence linking SAR to actual health effects. However, t= he=20 Kucinich Bill also calls for new research into cell-phone health effects=20= since past research found zip. The bill would also compel the Environment= al=20 Protection Agency to review and update its radiation-emission guidelines,= =20 despite the absence of any problem. We=92ve been down this road before. = The=20 power-line-radiation fiasco in the 1990s terrified millions of people who= =20 thought the fields from electric power lines in their homes might lead to= =20 childhood leukemia. It took years to convince the public that power-line= =20 fields are completely harmless. Many of those misled the public on power=20= lines are at it again on cell phones. 4. GUNS: THE ADVENTURE OF LIVING IN A WORLD WITHOUT GUN LAWS. Even as some in Congress seeks to protect us from feeble microwave photon= s,=20 anyone can obtain an assault weapon that spews out 100 lead bullets per=20= minute, each of which can blow half your head off. There is no=20 justification for allowing such weapons in a civilized society. =93Aye,=20= there=92s the rub.=94 THE UNIVERSITY OF MARYLAND.
